Question

If QS = 3x + 3, find x.

A) x = (QS - 3)/3
B) x = 3/QS - 3
C) x = QS/3 - 1
D) x = 3/(QS - 3)

Answer 1

To solve for x in the equation QS = 3x + 3, subtract 3 from both sides and then divide by 3. The correct formula for x is (QS - 3)/3, which aligns with answer choice A.

Step-by-step explanation:

The question is asking to solve for x in the equation QS = 3x + 3. To find x, we need to isolate x on one side of the equation. Here's a step-by-step solution:

1. Start with the given equation: QS = 3x + 3.
2. Subtract 3 from both sides to get QS - 3 = 3x.
3. Divide both sides by 3 to isolate x: (QS - 3)/3 = x.
4. Therefore, x = (QS - 3)/3.

From the answer options given, the correct answer is A) x = (QS - 3)/3.
